 ## Overview
 
-The Request Network API uses a **reference-based payment detection system** that automatically monitors blockchain transactions to detect when payments are made to your requests. This system works across multiple blockchains and handles various payment scenarios with zero configuration required.

 ## How It Works

 ### 1. Payment Reference Generation
 
-When you create a payment request, the API automatically generates a unique **payment reference** — a 16-character identifier that acts as a fingerprint for your request. This reference is what connects blockchain transactions back to your specific request.
+When you create a request, the API automatically generates a unique **payment reference** (16-character identifier). This reference is what links on-chain payment transactions to your request.
 
 **Example:** `0x1234567890abcdef`
 
 ### 2. Blockchain Monitoring
 
-The API continuously monitors supported blockchains using subgraphs that scan for transactions containing payment references. This happens automatically in the background with no action required from you.

 **Monitoring includes:**
-- Real-time transaction scanning
-- Multi-network support
-- Payment reference matching
-- Amount and currency validation

 ### 3. Automatic Detection
 
 When someone makes a payment and includes the payment reference in their transaction, the system:
 
-- **Detects** the transaction within minutes
+- **Detects** the transaction
 - **Validates** payment details (amount, currency, recipient)
-- **Updates** request status (pending → partially paid → fully paid)
+- **Updates** request status (for example partially paid or fully paid)
 - **Triggers** your configured webhooks
 
 ### 4. Real-time Status Updates
 
-Once a payment is detected, your request status is immediately updated and you can get the latest information via:
-
-- **API Queries:** GET requests to check payment status using the request ID
-- **Webhooks:** Automatically receive updates to your configured webhook endpoints

-## Supported Networks
+Once a payment is detected, your request status is updated and you can retrieve the latest information via:
 
-Payment detection works across all Request Network supported chains:
+- **API Queries:** `GET /v2/request/{requestId}`
+- **Webhooks:** receive updates on your configured endpoints

 ## Crosschain Payment Detection
 
-All crosschain payments using the Request Network API use the **ERC-20 Fee Proxy contract** as the final payment leg, ensuring payment detection works seamlessly across chains.
+All crosschain payments using Request Network API use the **ERC-20 Fee Proxy contract** as the last payment leg, so payment detection works out of the box.
 
 **How it works:**

-## Payment States
-
-Requests progress through the following payment states:
-
-- **`created`** - Request created, awaiting payment
-- **`pending`** - Payment transaction detected, awaiting confirmations
-- **`partially_paid`** - Partial payment received
-- **`paid`** - Full payment received and confirmed
-- **`overpaid`** - Payment exceeds expected amount
-- **`refunded`** - Payment was refunded
